Gags brought up a good point in another post. We have a new to us catcher on our team and she is pretty solid behind the plate. I have noticed that she leaves her throwing hand in a similar location. When I asked her about it, she said her catching coach tells her to do that. I told her my reasons why she needs to hide it or at least tuck her thumb.
She goes to our org catching coach and has been seeing him for a few years.
Anyone else seen something like this?
